pub fn smooth_terrain_risk(
cells: &[Vec<TerrainRiskCell>],
config: &RiskMapSmoothingConfig,
) -> RoboticsResult<Vec<Vec<TerrainRiskCell>>>Expand description
Smooth terrain-risk channels while preserving blocked-cell topology.
Blocked cells remain blocked. When smooth_blocked_cells is false, their
risk values are left untouched, but they still contribute to neighboring
risk smoothing.
